APPARATUS FOR MAKING HOLLOW TILES- SPEGIFIGA'IION forming part ofLetters Patent No. 765,579, dated July 19, 1904.

Application filed January 19, 1904. Serial No- 189,766. (No model.)

To all whom, it may-concern.-

Be it known that I, GEBHARD J AEGER, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a certain 5 new anduseful Improvement in Apparatus for Making Tiles, of which the followingis a full, clear, and exact description, reference being had to theaccompanyingdrawings, forming part of this specification, in whichFigure 1 is a front elevation of the apparatus. Fig. 2 is a plan view ofthe same. Fig. 3 is an end elevation; and Fig. 4 is a vertical sectionon the line IV IV, Fig. 2, showing the mold in position for dischargingthe product. .My invention relates to an improvement in apparatus formaking tiles which may be formed of concrete or any other suitablematerial; and it is especially adapted to forming what are known asconcrete blocks. the body of which is formed of concrete, and the facemay be formed of other or similar material having a finished surfacewhich may represent marble, granite, or any other stone or material. 7

I will now describe my invention, so that others skilled in the art maymanufacture and use the same.

In the drawings, 2 represents the frame of the apparatus, which may bemounted upon 3 wheels 3 to enable the apparatus to be readilytransported from one part of the building to the other, or a truck orother suitable means of transportation may be employed, as mostconvenient. Within the frame 2 is the mold 4, which may be formed ofcast-iron or other suitable material, the interior of the mold being ofthe form which it is desired that the tile shall assume. This mold 4 issupported by means of trunnions 5, which extend from 4 the ends of themold through suitable bearings 6 in the frame 2. In the outer ends ofthese trunnions 5 outside of the bearings 6 are cams 7, having cam-faces8. Above the cams cause the trunnions to move in and out, and

thereby cause the end leaves 11 of the mold 4 to open and close. Theseend leaves 11 are pivoted at their lower portions to the base of themold, so that the leaves may open and close with the movement of thetrunnions 5, the trunnions themselves being pivoted to shoulders on theouter faces of the leaves. The base-plate 12 of the mold 4 is designedto mold the imitationstone face of the tile. To this base-plate 12 ishinged the side leaf 13, provided with openings 14 for the passage ofthe reciprocating plungers 17. Opposite the side leaf 13 is theremovable side leaf 15, upon which the molded tile rests as it movesfrom the mold. In front of the mold 4 are hinged brackets 16, adapted toreceive the molded tile. In the rear of the frame 2 are two pl'ungers17, supported on a reciprocating carrier 18, to the rear end of whichcarrier are pivoted levers 19,, the ends of which levers are pivoted tothe frame 2 by a pivotal shaft 20. Pivoted to the levers 19 arecrank-arms 21, which at their other ends are pivoted to the cranks '22,mounted on the shaft 23 and operated by the hand-lever 24. By means ofthese arms and levers the carrier 18 may be caused to reciprocate andthe plungers 17 enter and recede from the body of the mold 4 through theopenings 14 in the side leaf 13 for the purpose of pressing the tile andforming the cavities therein. Secured to the outer end of one of thetrunnions 5 is a hand-lever 25, by means of which the trunnions 5 andthe cams 7, together with the mold 4, supported by the trunnions, may begiven a one-quarter revolution.

The operation of this improved apparatus is as follows: The mold 4 beingin its normal position, the open top of the mold being uppermost, thebase-plate 12 being in a horizontal position, and the side leaves 13 and15, both of which are provided with openings 14, being in a verticalposition, the clay, concrete, cement, or other material which is to beused to form the outer face of the tile is first placed on thebase-plate of the-mold to a thickness of an inch or more, according tothe material used and the block to be formed. The plungers 17 are thencaused to reciprosage of the plungers horizontally through the massedconcrete compresses the material which forms the face portion of thetile, and the plungers are also adapted to form the hollow cavitieswithin the tile when the mold is filled up with concrete or cement,which is done after the plungers have been moved into the mold. Theplungers 17 are then withdrawn by a reverse movement of the hand-lever24, leaving a molded tile within the mold.

In order to remove the tile from the mold, a quarter-revolution isimparted to the same by means of the hand-lever 25, which is keyed tothe trunnions 5, and this quarter-revolution not only lowers theremovable side leaf 15 to a horizontal position, but also bysmeans ofthe cam? bearing against the friction-rollers 10 opens the pivoted endleaves 11, which separates these leaves from the end of the molded tileand allows the molded tile resting on the movable side leaf 15 to beremoved from the mold by drawing the removable leaf forward to thehinged brackets 16, from which the removable leaf carrying the tile maybe removed to the drying-room.

Although I have described both end leaves as being movable, and this isthe preferable construction, I do not desire to limit myself thereto,'as one of these leaves may be fixed.

I have also shown and described double plungers. It will be apparentthat one of these plungers may be omitted where it is desirable to makea small tile.

I have also shown and described a mold of a certain shape adapted tomake rectangular tile. By changing the shape and dimensions of theleaves of the mold and also of the plungers tiles of other shapes may bemanufactured as, for instance, an L-shaped tile, adapted to use forcorner-pieces, may be manufactured by using a difierent shape in thebase and the side pieces being modified accordingly.

The advantages of my invention will be appreciated by those skilled inthe art. Owing to the fact that the face of the tile is formed on thebase-plate of the mold, the movement of the plungers instead of marringor distorting this face serves to press the same firmly against themolding-face.

A further advantage is found in the fact that there is nothing to marthis face of the tile or any of the faces of the same when the tile isremoved from the mold, for the reason that as the mold is thrown on itsside position the tile is removed from the same and separates from thenow vertical face of the mold without difficuty and without danger ofdistortion.

A further advantage is found in that the inner face of the tile is theunmolded face and is consequently left with a rough surface, whichwillmore readily'bind with the plastering of the building in which the tile*as they are laid in the building.

Although I have described the side leaf 13 as being hinged to'thebase-plate 12, it is removably secured to the said base-plate, so thatsaid side leaf 13 may be removed and one of different width substitutedin its place, 1

whereby tile of differentthicknesses may be formed, the removable plate15 being changed for one of equal size with the fixed plate 13. It will.be noticed that the removable plate 15 is supported by means of flanges26- on the base-plate 12 and the end leaves 11. flanges should beof'such width as to support the side leaf when the end leaves have been.opened in the manner already described.

On the end 'leaves'll are lugs or supporters 27, which engage with theside leaf 13 when the end leaves 11 are closed, making thereby a rigidmold which will not become distorted through the movement of theplungers 17.

Owing to the fact that the tiles are removed These from the mold by ahorizontal sliding movement, there is little danger of distortion of thetile through careless handling by the workmen, the tile coming out witha natural movement and resting on the brackets in front of the mold.

Having thus described my invention, what I claim,'and desire to secureby- Letters Patent, is p 1.
